| description | The invention relates to the field of waste heat utilization, in particular to a method for recycling waste heat of a boiler. The method comprises the following steps: S1, introducing boiler tail gasinto a desulfurization dust remover, and adopting hot water in the desulfurization dust remover to absorb sulfide gas in the tail gas; S2, introducing the tail gas discharged from the step S1 into a water heater and heating water in the water heater through the tail gas, wherein some hot water in the water heater is used as domestic water, and the rest of hot water is used for desulfurization after being introduced into the desulfurization dust remover; and S3, discharging the tail gas discharged from the step S2 into the atmosphere. According to the method, the tail gas is subject to desulfurizing and dedusting treatment first and is then introduced into the water heater to heat the water, so that corrosion of equipment is avoided, the heat utilization rate is improved, and a good use effect is achieved.
